Question

Modulus of rigidity and unit & dimension

Answer 1

Answer:

the derived sl unit of shear modulus is the Pascal ( pa ) , although it is uselly expressed in gigapascal (GPa) or in thousand of pounds per square inch (ksl ) . it's dimensional form is M1L - 1T - 2 ., replacing force by mass time acceleration.

hope it help you

please mark as brainliest answer

Answer 2

Answer:

Modulus of rigidity formula is

G = E/(2 (1+v))

And modulus of rigidity is G .

S.l. unit = Pascal .....
